Abstract

A method and apparatus for increasing the speed of scanners reading multiple bar code symbologies by changing the order of priority in which the various symbologies are tested by the decoder. After a particular symbology has been read a given number of times in a row, its priority is increased. A particular symbology will continue to advance in priority the more often it is read until it becomes the highest priority symbology.
